Portable traveller headrest

Abstract

A portable traveller headrest is provided. The portable traller headrest includes a bar that may be articulated so that it can be folded onto itself, the ends of said bar having transversal holes to fix the bar to a seat with a fixing mechanism that adapts to different thickness of a top edge of various seats and fixes the bar to a backrest of the seats by pressure and at a desired height chosen by the user. Headrest elements, which comprise thin plates made of a rigid material and have a cushioned cover, can be connected, disconnected and rotated in discrete positions relative to the bar . The fixing mechanism is hingedly mounted in holes located on the bar, thereby requiring little space for storing the assembly.

1. A portable traveller headrest device with a light-weight structure, made of low specific weight non-metallic material, that can be adapted by the user for seat backrests having various heights and thicknesses without altering the shape of the seats to which it fits, the device comprising:
 a ribbed support bar including two pieces joined by a hinge that permits the pieces to be folded together thereby reducing a length of the bar to facilitate storage and transportation of the device, the pieces having a narrow rectangular cross-section and including two semi-cylindrical projections with polygonal holes proximate to lengthwise ends of the bar; and  
 two side headrest elements adapted to couple with the polygonal holes and adjustable to an angular position selectable by the user.  
 
   
   
     2. A portable traveller headrest, according to  claim 1 , wherein the side headrest elements comprise:
 two light-weight rigid thin plates;  
 a cushioned cover disposed on a side of each of the plates; and a pivot for adjusting the plate to an angle, with respect to a backrest surface.  
 
   
   
     3. A portable traveller headrest, according to  claim 2 , further comprising two inverted U-shaped mechanisms that are each adapted to couple with a cylindrical hole disposed on the pieces proximate each of the semi-cylindrical projections so that the mechanisms depend rearward from the bar to hook over a seat backrest, each mechanism comprising two independent L-shaped pieces that slide over each other allowing a width of the U-shaped mechanism to be increased or diminished, thus adapting itself to seats of different thicknesses. 
   
   
     4. A portable traveller headrest, according to  claim 3 , wherein a vertical portion of the L-shaped piece coupled with the bar includes a longitudinal slot that allows vertical adjustment of the bar relative to a horizontal portion of the U-shaped mechanism. 
   
   
     5. A portable traveller headrest, according to  claim 1 , further comprising: two inverted U-shaped mechanisms that are each adapted to couple with a cylindrical hole disposed on the pieces proximate each of the semi-cylindrical projections so that the mechanisms depend rearward from the bar to hook over a seat backrest, each mechanism comprising two independent L-shaped pieces that slide over each other allowing a width of the U-shaped mechanism to be increased or diminished, thus adapting itself to seats of different thickness. 
   
   
     6. A portable traveller headrest according to  claim 5 , wherein a vertical portion of the L-shaped piece coupled with the bar includes a longitudinal slot that allows vertical adjustment of the bar relative to a horizontal portion of the U-shaped mechanism.
